To all whom it may concern:

Be it known that I, FIHGDIGR'ICXC ll. Parse, a citizen of the United States. residing at Marinette, in the county of Mariuette and State ot Vi iscrmsin, have invented new and useful InuJn-ovennmts in Invalids lieds, of which the following is a specification.

This invention relates to improvements in invalids beds, the primary object of the ii'i'vention being to provide a bed of this character which is simple of construction, susceptible of n'lanu'facture at a comparatively low cost, and embodies head and foot sections independently adjustable to different. heights or angles to suit the convenience of the patient and dispose the parts in ditterent positions as ocasion may dennmd.

A further object of the invel'ition is to provide a bed of this clmracter embodying a novel construction of self-locking gearing tor adjusting the head and foot sections, and which bed, while self-supporting, may be easily and conveniei'itly positioned upon an ordinary bedstead.

With these and other objects in view, the invention consists of the features of corn strnction, combination and arrangement ot parts, hereinafter fully described and claimed, reference being bad to the accompanying drawing, in which liigure 1. s a perspective view of: an invalids bed constructed in accordance with my invention, and illustrating in tall and dotted lines different positions of adjustment of the h aid and toot sections. Fig. 2 is a longitudinal section, showing the device supported upon an ordinary bedstead. Fig. 3 is a sectional plan view of a portion of the gearing. Fig. L is a detail view, showing the construction of one of the supporting legs.

Referring to the drawings, 1 designates the substantially rectangular frame of the bed, which may be made of any suitable material. This frame 1 is provided at its corners with pivoted leg lHOlTll'JOl'S 2, each carrying a pivoted folding brace having a hooked free end 4: to engage a keeper member 5 upon the frame. The legs and braces are adapted to be folded upon the inner faces of the longitudinal members of the frame when the latter is supported upon a bedstead, as illustrated in Fig. 2.

Arranged on opposite sides of the transverse center of the frame are transverse hanger bars 6, disposed below the plane of the frame and having upturned ends 7 secured to the side pieces of the frame. These bars support a centrally disposed longitudinally extending bracket on which is ar ranged a knigitudinally extending strip 9 having upturned ends it). The ends 10 'form bearings tor longitudinally extending shafts 11, the outer ends of which are journaled in said bearings. Mounted upon the bracket 8 between the bearings 10 is a boxing 12 forming a bearing for the inner ends of said longitudinally extending shafts, as well as for the inner ends of transversely extending shafts til. The said inner ends of the longitudinally extending shafts I1 '1. are. provided with miter gears 1 1-, and the inner ends of the trmisversely extending shait'ts 1 are provided with miter gears '15, each gear it being in mesh with one of the gears 15, whereby upon rotating the transverse shafts the longitudinally extending shafts may be independently operated. As shown, the shafts 11 are screw-thrcadcd and disposed on opposite sides of the transverse center of the bed and in longitudinal alinement with each other.

The bed bottom consists of a fixed or nonadjustable central section it) preferably formed of woven wire secured to the side bars of the frame and vertically swinging head and foot sections 17 and 15, each consisting preferably of a substantially U shaped frame portion '19 covered by woven wire fabric 9t), the fabric portions 20 being either secu red to or forming an integral part of the central fabric section It) so as to provide a bed bottom which is continuous or without break. The inner ends of the head and foot sections are pirotally mounted to swing upon pins or bolts 91. and each is provided at the inner ends of its side arms with depending cranks 22 connected by a cross rod said cross rod being rein't'tn-eed from the end piece of the section by braces 25.

Secured to each rod 2 is a cross head or strip 26 carrying an inwardly extending yoke 27 secured at its outer closed end to said strip and pivotally connected at its inner free ends to the sides of a follower or traveler 28, as indicated at 2!), the arms 22, rod 2?). and cross head Qt) constituting a, crank element for imparting mot-ion to the swinging section, as will be readily understood. Thc follower or traveler 28 comprises a block having an internally threaded bore engaging the adjacent screw shaft 11 and forming a nut which is adapted to travel upon said shaft and to carry the yoke with it, the sides of the yoke being arranged to embrace the adjacent bearing 10 and to travel along opposite sides of the shaft 11, whereby said parts of the gearing are partially housed and protected to a large extent from liability of injury. The outer ends of the shafts 13 are journaled upon and project beyond one of the longitudinal side pieces of the frame and have angular extremities 30 to receive a crank handle or wrench whereby either of said shafts may be rotated.

From the foregoing description, it will be apparentthat when the nuts or followers are in a substantially central position on the screw shafts the head and foot sections will be in normal position, or arranged to lie in the plane of the bed frame, but that by operating the transverse shafts in one direction or the other, said sections may be independently adjusted to different heights or angular positions both above and below the plane of the main frame, so that they may be disposed to suit the convenience of the patient or as circumstances may require in the use of the bed. It will also be apparent that the screw gearing will be self-locking, so that the head and foot sections will be automatically held in any of their positions of adjustment. Upon folding the supporting legs the bed may be mounted upon an ordinary bed stead or used as a stretcher, and upon unfolding and locking them in normal position the bed will be supported at a desired elevation above the floor surface. It will be seen that the construction is simple and comparatively inexpensive and provides a means whereby a patient may be supported in a variety of positions as circumstances may require.

Having thus described my invention, 1 claim 1. A bed of the character described embodying a main frame, a. swinging section provided with a crank element, a longitudinally extending screw shaft, inner and outer bearings for said shaft, a traveler movable longitudinally on the shaft, a yoke coupled to the crank element and traveler, the arms of said yoke being pivotally connected with the traveler, and means for operating said shaft.
